There already have been reports that the Broncos will try to acquire Colin Kaepernick from the San Francisco 49ers, and there is growing speculation that Robert Griffin III also is on the team's radar following his release from the Washington Redskins.

With Brock Osweiler off to Houston, RGIII is on Broncos' list of replacement quarterbacks, per source. Could be visiting Denver.

RG3 last appeared in a regular-season game during the 2014 season, when he played in nine games and started seven. This past season, he was firmly planted on the bench behind Kirk Cousins (and McCoy).

But it was just three seasons ago that Griffin electrified the NFL, being named the AP Offensive Rookie of the Year after throwing 20 touchdown passes with just five interceptions (and rushing for 815 yards and seven scores). Of course, that was before the ankle and knee injuries, and the inconsistency.

But Denver just won a Super Bowl on the strength of its defense, with an aging quarterback playing the role of game manager. Is that a role RG3 could handle?
